Denison smock
The Denison smock was a coverall jacket issued to Special Operations Executive (SOE) agents, the Parachute Regiment, the Glider Pilot Regiment, Air Landing Regiments, air observation post squadrons, Commando units, and other Commonwealth airborne units, to wear over their Battle Dress uniform during the Second World War, remaining in service with the British Army until the early 1970s when it was replaced by a version in the Disruptive Pattern Material (DPM) smock. The garment was also issued as standard to the scout and sniper platoons of line infantry battalions.
